Bronchitis Vaccine (Mass. Type, Freeze-dried)

Bronchitis Vaccine (Mass. Type, Freeze-dried) Indications

This vaccine contains Massachusetts type bronchitis virus. It is recommended for the vaccination of healthy chickens at one day of age using the eyedrop method, or at seven days of age or older using the drinking water or coarse aerosol spray. It is essential that the chickens be maintained under good environmental conditions and that exposure to disease viruses be reduced as much as possible.

Store at 35-45°F (2-7°C). Do not freeze. Do not vaccinate within 21 days of slaughter. Use entire contents when first opened. Burn this container and all unused contents. Contains Streptomycin Sulfate and Penicillin as bacteriostatic agents and Amphotericin B as a fungistatic agent.

Intraocular Vaccination

The vaccine used for intraocular vaccination is accompanied by diluent and is recommended for the vaccination of healthy chickens one day of age or older using the 1,000 dose or 2,000 dose vial.

4. Withhold all water from the chickens for a minimum of two hours in warm weather to four hours in cool weather prior to vaccination to stimulate thirst. Withdrawal time should be reduced if half-house brooding is in process.

5. Do not open or mix vaccine until ready to vaccinate.

6. Drinking water for vaccine delivery should contain one ounce (29 gram) of non-fat dry milk per gallon (3.8 liters) of non-chlorinated water, or should contain milk product based stabilizer prepared according to the manufacturer’s instructions.

7. Reconstitute the vaccine in 3 gallons (11 liters) of milk-water during cool weather or 4 gallons (15 liters) of milk-water during warm weather for each 1,000 doses.

8. Distribute vaccine solution among waterers. Avoid direct sunlight.

9. Lower waterers and allow the chickens to drink freely. Add the remaining vaccine solution to the water lines as the chickens drink.

10. Do not provide additional drinking water until all the vaccine is consumed.

Drinking Water Vaccination Using Proportioner Application

Drinking water vaccination is recommended for healthy chickens seven days of age or older. Several types of medicator/proportioners are commercially available. Set proportioner to deliver one ounce (30 ml) of vaccine concentrate per one gallon (3.8 liters) of water.

1. Remove all medications, sanitizers and disinfectants from the drinking water 72 hours (three days) prior to vaccination.

2. Clean all containers, hoses and waterers prior to vaccination.

3. Withhold all water from the chickens for a minimum of two hours in warm weather to four hours in cool weather prior to vaccination to stimulate thirst. Withdrawal time should be reduced if half-house brooding is in process.

4. Do not open or mix vaccine until ready to vaccinate.

5. Calculate to supply vaccine solution at a rate of 3 gallons (11 liters) per 1,000 chickens in cool weather and 4 gallons (15 liters) per 1,000 chickens in warm weather. The age of the chickens should be considered when calculating water supply. Always use non-chlorinated water when vaccinating chickens.

c. Reconstitute the dried vaccine with the milk solution. Rinse the vaccine vial to remove all the vaccine.

7. Insert proportioner hose into the vaccine stock solution and start water flow. Continue until all solution has been consumed before changing water supply to direct flow.

8. Do not medicate or use disinfectants for 24 hours after vaccination.

Coarse Aerosol Spray Application

Coarse aerosol spray application is recommended for vaccination of healthy chickens seven days of age or older. Use a sprayer delivering a coarse aerosol spray pattern to dispense rehydrated vaccine quickly and evenly throughout a house of chickens. Do not use vaccinating equipment for any other purpose.

1. Prior to spraying, reduce air flow by raising curtains or stopping fans. Air movement should be limited for 20 minutes following vaccination.

2. Do not open or mix vaccine until ready to vaccinate.

3. Fill vaccine container with cool, distilled water.

4. Pour reconstituted vaccine into a clean container and add 5 ounces (150 ml) of cool water for each 1,000 chickens to be vaccinated.

5. Place the vaccine solution into spray canister and walk through the house spraying at the rate of 1,000 chickens per minute. Aim spray directly above the heads of the chickens.
